BOSTON — Had 'em all the way.

New England fans were treated to two of the most improbable comebacks they'll ever see Sunday. After Tom Brady's Patriots heroics, the Red Sox fashioned a hard-to-fathom 6-5 win over the Detroit Tigers in Game 2 of the American League Championship Series.

The series is knotted at a game apiece and switches to Detroit for Game 3 on Tuesday afternoon.

Down 5-0, Boston came back with a run in the sixth on Dustin Pedroia's RBI single, scoring Shane Victorino.

In the eighth, with starter Max Scherzer out of the game, the Sox loaded the bases on three relievers. David Ortiz came to bat, and the Tigers countered with closer Joaquin Benoit.

Ortiz won the battle. He hit the first pitch into the right field bullpen, tying the game at 5-5 and sending Fenway Park into delirium.

Koji Uehara, who notched the win, got the Tigers 1-2-3 in the ninth, setting up Boston's walk-off heroics.

Jonny Gomes led off with an infield single and took second base on former Sox shortstop Jose Iglesias' errant throw.

Gomes took third on a wild pitch and scored on Jarrod Saltamacchia's single through a drawn-in infield.
